A quick note. I think the Poke Pro would suit most of your needs. Yeah, it ain't cheap. Also consider the Likebook Mars. A point about the Poke Pro: Google Playstore does not work out of the box. It is installed, but Google does not recognize the device as valid. It's a new Google thing. There is, I believe, a simple workaround, but I don't know it and I haven't done it. Apparently the user bookter in Germany who sells Boox's knows it.
